IMPROVEMENT IN ROTARY WATER-Mareas.

Specication forming part of Letters Patent No1-947,349, dated December 1l, 1877 5 application Afiled September 17 1877.

. is a vertical central section of the same; Fig.

3, a cross-section ion the lower part `of the meter; and Fig. 4 a ,detailed face view ofthe `plates for holding and adjusting the inletpipe.

Similar letters of reference indicate corresponding Vparts in all the figures.

' This .invention relates to certain improvements in vthe construction and arrangement .of .the inlet-.pipe of a water-meter and has for its principal object to obtain a current of water `at such an angle within the meter as will utilize to the best effect the power of the water upon the mechanism of the meter.

To this end I make a vibrating inlet-pipe, and place it adjustably within the mouth of the meter, so that it extends into the body of the meter, and so that its angle may be varied according to the size or power of the current; and I further provide this inlet-pipe with an angular or tapering end, and also with a similarly-shaped lid or valve, which is held against the mouth of the pipe by a spring, so that the water opens the said lid or cover to an extent corresponding to the degree of pressure and the size of current.

By virtue of the tapering form of the pipeV and valve or cover, the stream that enters the meter is automatically retained compact, and

' its size regulated and made quite small where there is but a small amount of water admitted to the pipe, and correspondingly larger where more water is admitted.

The invention further consists in other details of improvements hereinafter more fully pointed out.

extends intothe body of the meter-box, within the periphery thereof, as shown.

I propose to close the mouthof the meterbox by means of two sliding plates, C D, which .are more fully shown in Fig. 4., and which are, by suitable screws I), fastened to lthe end of the box. They have semi,circular recesses cut into their conti'gufms ends toV properly embrace the inlet-pipe, and are slotted where the screws b pass through them; They are in `consequence laterally adjustable on the meterbox, to permit a `corresponding adjustment of the angleof the inlet-pipe. The inlet-pipe litself is provided with ,two projecting pins, d d, Which ,are diametrically opposite each other, `and which enter ,into recesses ctha-t 4Tf1-1T@ formed in the lendof the meter-box, as indicated by ,thedotted lines in Fig. l, and on these pins or pivots d the inlet-pipe Bean bevibratedo that litsangleof entrance into the meter-box maybe varied at will, the plates C J) serving `to hold itat any desired angle.

By this adjustment of the inlet-pipe I am enabled toincline the stream of water that enters vthe meter more or less, as may be required under varying circumstances. By extending the pipe B into the body of the meter-box, I am enabled to direct the water against thewings of the registering mechanism at the most preferable angle. The inner end'of the inlet-pipe is made with a 4tapering or rather triangular discharge-opening, `of which the smaller end projects farthest into the meter, and is nearest to that side of the meter-box or mechanism which is the first to be reached by the current of water.` This triangular or tapering opening is covered by a similarly-shaped valve or cover, E, which is by a spring, f, held over the opening, vto entirely close the same if no water is admitted. The valve E has two lips, g g, that lap over the sides of the tapering aperture above referred to, and prevent the lateral discharge of water from the pipe B. The valve Eis at its base or broader portion pivoted or hinged to the broader portion of the discharge end of the inlet-pipe, as indicated at h, in Fig.' 1.

It will be readily seen that a stream of Water entering the pipe B will, by pressing against the valveEmore or less, open the s ame according to the size andpower of the current, and that the smallest possible current will still be maintained compact, because a small and narrow opening only will be formed by a par-4 tial opening of the valve. This is in contradistinctionv to those constructions of inlet which only vary the size of the current in thickness and not in the breadth, whereas in my meter the opening' will become wider and broader the more the valve is opened, and it will be narrower and thinner the more the valve is closed, thus maintaining the power of the current properly collected for eilect upon the mechanism of the meter. The spring j' should, of course, have its power regulated according to the locality in which the meteris set up, and for this purpose I provide the inner face of the valve E with an inwardlyprojecting perforated plate z', and I also provide the outer end of the inlet-pipe with a notched or perforated cross-bar, j. The power of the spring is regulated by hooking its ends into any one of the different apertures of the plate and into any desired one of the several notches or apertures of the cross-piece or bridge j. Nearly opposite the discharge end .of the inlet-pipe I also place into the meterinletpipe, and the other features of the invention which I have pointed out, may beV used either alone,in the manner shown in the drawing, or on meters having additional passages for carrying part of the current past the meter. In the illustration, a meter is shown which carries the entire current through the meter.

I claim as my inventionl. The inlet-pipe B, made to project into the meter-box proper, and extend within the inner periphery thereof, in line with the buckets of the wheel, substantially as and for the pur pose shown and described.

2. The inlet-pipe B, placed adjustably into the mouth of the meter-box, and combined with regulating-plates C D, substantially as speeiied.

3. The inlet-pipe B, made with a triangular or tapering discharge-opening within the inner periphery of the 1neter-box, and in line with the buckets of the wheel, substantially as specified.

4. 'Ihe tapering or triangular valve E, provided with the lips g g and combined with the inlet-pipe B, having the tapering openings, substantially as specified.

5. The pivoted inlet-pipe B, hung on trunnions or pins d d, having tapering dischargeopening, and combined with ameter-box, sub-Q stantially as herein shown and described.

6. A water-meter provided with the pivoted direction-plate F, which is combined with the adjusting-screw k, substantially as herein shown and described.
